the kinetic of photo oxidative decolorization of c.i. acid yellow 23 (ay23) was investigated in uv/ process. the semi-logarithmic of the concentrations of ay23 versus irradiation time were linear, suggesting pseudo-first order reaction. a simple kinetic model is proposed which confirms pseudo- first order reaction. the results indicate that the apparent reaction rate constant is a function of l...

The cell growth and product formation kinetics of anaerobic biohydrogen production by mixed anaerobic cultures was investigated using unstructured models in the present study. They described the realtionship between biomass growth and product formation in the hydrogen production process. Experimental results show that the Logistic model and LeudekingPiret model could be adopted to describe the ...

the aggregation of protein is the most prevalent and the most disturbing kind of instability and this challenge exists in almost every stage of the development of protein drug. the presence of insoluble aggregations in protein drugs will make the supply of the product a tough job. this study identifies the inhibition of the folded interferon beta 1-b’s aggregation with the assistance of some ex...

this study is focused on the development of a systematic computational approach which implements genetic algorithm (ga) to find the optimal rigorous kinetic models.a general kinetic model for hydrogenolysis of dibenzothiophene (dbt) based on langmuir-hinshelwood type has been obtained from open literature. this model consists of eight continuous parameters(e.g., arrhenus  and van't hoff paramet...

Simple kinetic models of carbon nanotube growth have been able to successfully link together many experimental parameters involved in the growth of carbon nanotubes for practical applications including the prediction of growth rates, terminal lengths, number of walls, activation energies, and their dependences on the growth environment. The implications of recent experiments utilizing in situ m...

mathematical modeling and simulation of microbial polyhydroxybutyrate (phb) production process is beneficial for optimization, design, and control purposes. in this study a batch model developed by mulchandani et al., [1] was used to simulate the process in matlab environment. it was revealed that the kinetic model parameters were estimated off the optimal or at a local optimal point. therefore...
